- a decrease in temperature
- an increase of the particles dimensions
- lack of stirring
Cold Temperature
Ammonium hydroxide only exists in solution and is formed by dissolving ammonia in water. The solid cannot be isolated
By irritating a solution, increasing the concentration of the solute, by increasing the temperature
It is both:It is a physical property because the solid salt becomes part of the liquid state of the water.It is a chemical property because the act of dissolving in water changes the salt (NaCl) into separate ions.
The solubility of solid materials increase when the temperature increase; it is a general rule.
You reach the solubility of salt in water when the salt stops dissolving and settles at the bottom, no matter how hard you try to mix it. You can increase solubility by increasing the water temperature.
Break up the solid
is dissolving a chemical or physical changeWell, it is not. Because you are not changing the chemical identity of the solid. It's still solid chemically and water chemically.
Dissolving in water is a physical change.
Dissolving is what happens to sugar when you put it into hot water. It goes from being a solid to being a liquid. Soap, when placed in hot water, will also dissolve.
Stirring, heating, crushing the salt
Water; it is polar.
A water solution of this medicine is obtained.
Apex - It makes the water molecules bump into the solute more. ^.^

physical change- solid to solution
Examples: rising of temperature and stirring.
The process of dissolving is and can be aided by stirring, swirling, or shaking. However there are other factors which can determine the rate a solute dissolves in a solvent. One such factor is temperature. Example: sugar dissolves faster in hot tea rather than in cold..
